Improved Classification Systems Needed for AAV, Study Shows

The autoimmune condition ANCA-associated vasculitis (AAV) needs improved classification systems that can better predict disease outcomes, a Spanish study says. Disease management should be based more on individual patient characteristics and levels of disease severity than on general classifications or ANCA specificities, the researchers suggest. The study, “…

Intravenous Immunoglobulin Quickly Lowers Disease Activity in AAV Patients, Review Study Finds

Intravenous immunoglobulin (IVIG) therapy leads to a fast and significant reduction in disease activity, as well as in the levels of inflammatory biomarkers, in people with ANCA-associated vasculitis (AAV), a review of several studies found. The study, “The therapeutic efficacy of intravenous immunoglobulin in anti-neutrophilic cytoplasmic antibody-associated…

ANCA Autoantibodies Produced in Healthy People, Study Shows

Healthy individuals also produce a type of self-reactive antibodies — termed IgM ANCA — present in people with ANCA-associated vasculitis (AAV), a study has found. While low, the levels in healthy people are comparable with those in AAV patients whose disease is less active. The antibodies’ role is still…
